Interesting.  Both you and Klaus indicated that you had problems with
getting Ultra DMA from working, but I had no problems using a stock
2.4.21-rc1 kernel:

ICH4: chipset revision 1
ICH4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0x1860-0x1867, BIOS settings: hda:DMA, hdb:pio

hda: TOSHIBA MK6022GAX, ATA DISK drive
blk: queue c0371f40, I/O limit 4095Mb (mask 0xffffffff)
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14

hda: host protected area => 1
hda: 117210240 sectors (60012 MB), CHS=7752/240/63, UDMA(100)

Here's the hdparm -i /dev/hda and hdparm -tT /dev/hda output:

# hdparm -i /dev/hda

I didn't have to do anything special at all....

I'm using APM, which works just fine with my T40p.  The problems with
ACPI I think are with the ACPI implementation, not with the laptop;
ACPI support in linux is pretty primitive, unfortunately.
